Final answer:
Elevated liver enzymes and symptoms of common bile duct obstruction suggest the client may have gallstones, which leads to the correct diagnosis of option (c) from the provided choices.
Step-by-step explanation:
The client admitted to the hospital with symptoms of obstruction of the common bile duct and elevated liver enzymes may be suffering from gallstones. These stones can block the bile duct, preventing bile excretion, leading to the accumulation of bilirubin in the blood, and causing jaundice.
Elevated liver enzymes suggest that the liver is responding to some form of blockage or inflammation. Evidence of obstruction in the bile ducts and associated jaundice would lead to an increase in conjugated bilirubin in the blood. The liver function tests (LFTs) would reveal elevated enzymes such as alkaline phosphatase (ALP), occurring with large bile duct obstruction.
Considering the symptoms and laboratory results, the correct option for this scenario would be gallstones, which is option (c). Gallstones can indeed cause an obstruction in the common bile duct, leading to elevated liver enzymes. Other possible causes like acute viral hepatitis, cholecystitis, and pancreatitis are less likely to be associated principally with a common bile duct obstruction unless they also coincide with gallstone formation.
